Get started with MDS by Vivek Garg

Oracle has introduced couple of new features in Oracle SOA Suite 12c. I have listed couple of new features that Oracle introduced for developer in my post. These new features really make developers life easy as these reduce development cycle.
Here we discuss about MDS and what all featured introduced in that. As we know MDS is used to store artifacts like WSDL, XSD, XSLT etc. we have two types of MDS, File based MDS and DB based MDS. In Oracle SOA 12c, when we use default server which is integrated with Jdeveloper then we can use only Design Time MDS (File Based MDS), Run Time MDS (DB Based MDS) is not supported. Check this post to create design time MDS connection. In Oracle SOA 12c release, Oracle provided couple of new options that we can use when we use Design Time MDS, these options were not there in 11g. Below are options available with Design Time MDS. vivek

  • Create and Delete folders
  • Export and Import MDS artifacts
  • Transfer Artifacts between MDS repositories

In this post, we discussed these options one by one. Get started with Oracle SOA 12c.
Create and Delete Folders
We can simple add and remove folders from design time MDS repository. To add a new folder to it, simply right click on the apps folder and choose “Create Folder”. Read the complete article here.

Remove data in Oracle MDS by Danilo Schmiedel

The two main database schemas in the Oracle SOA Suite datab ase repository are: <PREFIX>_SOAINFRA and <PREFIX>_MDS. Composite instance and runtime information are stored in the SOAINFRA schema. Commonly used metadata like WSDLs, XSDs, rules, fault policies, etc. as well as composite deployments are stored within the MDS schema.
With every deployment / import of the metadata artifacts a new document version will be created in the MDS. This means that re-importing an updated WSDL-file into the MDS does not delete the previous version of the document. Furthermore we sometimes need to remove unnecessary and unwanted files from the repository. If this is not considered you might end in problems like below: Read the full article here.

Using the MetaData Services (MDS) in a SOA environment by Robert van Molken

It has been almost a year since my last post about the metadata services. I talked about how-to set up a File-based MDS and DB-based MDS. This post talks about the usage of the files, placed in the MDS, in the different components available in a SOA composite. If the MDS is a new thing for you then I advise to read my previous about this subject first.

You can spot the presence of a file that is a reference to the MDS if it uses the oramds: URI annotation. Files are no longer referenced to a hardcoded or relative file path.

To start using you’re MDS that you have set up we will create a new SOA application. Let call the application WorkflowSOAapp and create a SOA project and call it WebformService.

Use MDS resources for exposed services

After creating the new SOA project it will open the composite editor automatically. Exposed services are always created in the left swim lane. Because this project deals with a WSDL resource to expose a webservice, a Web Service component is first dragged to the left swim lane.

Create exposed service

Drag Web Service Component to left swimlane

A dialog “Create Web Service” will open. Give the service a good name, preferred the same as the name in the WSDL (e.g. WebFormService). The next thing to do is to choose the WSDL URL. Click on the document jdev_document_iconicon at the right side of the WSDL URL input to find an existing WSDL. Read the full article here & Read part II here.
